All the elemental swords except Clarent (as far as I've researched) seem to have some sort of historical account. Excalibur is the well-known sword of Arthur, Joyeuse was Charlemagne's personal weapon, and **spoilery**, though not at all well-known, seems to have been the sword of this too is too spoilery
. But Clarent... well, Clarent doesn't seem to be known at all! In fact, its only reference is in a Medieval English Poem, and appears to have been used for knighting ceremonies and other peaceful encounters. It was stolen from Arthur and used by Mordred to kill him.
Now we all know the classic tale of Arthur pulling out the Sword in the Stone and becoming king. Everyone assumed it was Excalibur. Now, there is also the myth of the Lady in the Lake, who gave Excalibur to Arthur as a loan to be returned later. Now, we seem to have a paradox here! Excalibur was possessed by Arthur from even before he was king, but after he became king, the Lady in the Lake gave it to him? I think not.
So my theory is this: the Sword in the Stone was Clarent, and the Lady in the Lake gave Arthur Excalibur. Now, because of their similarities in the hilt and because Arthur preferred Excalibure more than Clarent, I believe Clarent was completely forgotten, and Excalibur became the only mythological sword. Or maybe they combined... and Arthur simply continued to call it Excalibur. And Mordred split the swords and took one of them: Clarent. Anyway, I'm starting to think we need a thread for the Elemental Swords, because there's too much about them to put anywhere else! Or is there already a thread for them? Because if there is, I haven't been able to find it!
